Hi everybody,
 
How can I check wheter I'm receiving multicasts? I have recompiled the
kernel and I'm running mrouted but I can't get fazzt to work.
This is the mrouted.conf I use:
----/etc/mrouted.conf ---
cache_lifetime 3600             # seconds
pruning off
dvbauto on
#
phyint dvb0 altnet 128.0.0.0/1 altnet 125.0.0.0/1
phyint eth0
phyint eth1
 
---end of /etc/mrouted.conf--- 
This is the layout of my network:
 
-------------            ppp0  -----------------------------  eth0
|internet|---------------------|  Linux Box           |-------------no
multicast clients
------------                     |  running dvbd &    |
                                 |  mrouted              |
-------                  dvb0 |                            | eth1
|eon|--------------------------|                           
|------------- multicast clients
-------                          -----------------------------
 
Where ppp0 is a cable modem with a dynamic ip adress
dvb0 is 192.168.4.1
eth0 is 192.168.2.1
eth1 is 192.168.3.1
Client are in the same range, the one I'm trying fazzt on is 192.168.3.2.
 
I think mrouted is working because when I start I get the following out
put:
